1 General Information
1.1 Wireless magnetic contact security Detector «Ladoga MK-RK» ver. 4
(hereinafter, the Detector) is intended for opening or shifting control
of doors, windows or other structural elements with transmission of
messages to the control panel (hereinafter, CP) via two-way wireless
communication by the «Rielta-Contaсt-R» protocol.
1.2 Opening or shifting control is fulfilled by built-in magnetic contact
state monitoring.
1.3 The Detector operates within 433.05 – 434.79 MHz frequency
range. Transmission power does not exceed 10 mW.
1.4 The Detector ensures operation at the main and backup operating
frequencies. The changeover to backup operating frequency is fulfilled
automatically.
1.5 Radio communication is initiated by the Detector at 10, 15, 30 sec,
1, 5, 10 min intervals assigned in the process of their binding with the
CP. Alarm and tamper messages are transmitted immediately.
1.6 The Detector is powered by the one lithium power supply battery
CR123A.
1.7 The Detector generates and transmits the following messages:
- «Norm» – under closed built-in magnetic contact;
- «Alarm» – under opened built-in magnetic contact;
- «Tamper» – in the event of case tampering;
- «Power Supply Low Battery» – under the power supply battery
voltage drop over 2.2-0.2 V.
1.8 The Detector is designed to operate continuously, around the
clock.
1.9 The Detector has immunity to electromagnetic interference.

4 Design
The Detector consists of a case cover and a base with installed
printed circuit board (PCB) (1). In the base openable fixation holes are
located in the bottom (6) and in side wall (8). The PCB comprises:
battery holder (2), RESET contacts (3), tamper contacts (4), built-in
magnetic contact (5) and antenna (7).
For built-in magnetic contact management, master element (magnet) (9)
is used (supplied).

5 LED Indication
The following types of indication are generated by the Detector:
- «Binding»– procedure of logging of the Detector in the CP;
- «Identification»indication is activated by relevant commands received
from the CP, remains active during 15 min or until the Detector cover
is opened;
- LED indication of the Detector state is activated after the Detector
cover is closed and remains active during 15 min under conditions:
- other LED indication types absence;
- alarm «Tamper»message is not generated during this time;
- absence of command from the CP disabling the Detector state
indication.
The modes of LED indication are listed in Table 3.

6 Binding with the CP
The «Binding»mode is intended for the Detector logging in the CP
and service information exchange.
6.1 Prepare the CP in accordance with CP Installation Guide.
6.2 Observing the polarity install power supply batery to the holder if
power supply battery is installed in the holder (2), remove an insulating
film.
6.3 Periodical LED indicator blinking green is evidence of binding
process.
6.4 In case of mentioned above LED indication absence, short-circuit
«RESET»terminals for 2 – 3 sec.
6.5 Successful binding procedure complying is indicated by LED
indicator lighting red for 2 – 3 sec.
6.6 The time limit for the binding process of the Detector is 70 sec.
To restart the binding procedure, short-circuit «RESET»terminals for
2 – 3 sec.
7 Communication Quality Appraising
7.1 For radio communication quality appraising it is necessary to:
- set the Detector on the assumed place of installation;
- push and then release case tamper.
7.2 After case tamper releasing the Detector generates case
tamper alarm message, transmits it via radio communication channel
and represents communication quality with CP by LED indication in
accordance with the Table 4.
